摘要

摘要: 以苏北地区为例, 在分析区域岩石学、构造地质学和成矿学资料的基础上, 结合江苏省地质调查院和江苏省地质矿产局第六地质大队有关区域地质调查和矿产资料, 初步建立了2个成矿系列, 即与超高压变质作用有关的金刚石-金红石-蛇纹石-蓝晶石-大理石成矿系列和与高压变质作用有关的磷-水晶-蓝晶石成矿系列.前者与印支期巨量物质超深俯冲有关, 后者与稍晚发生的高压-超高压变质带的折返事件有关.本区可能存在燕山期金、银多金属成矿系列, 在下一步地质找矿时值得注意.

Abstract: Many deposits occur in the high-pressure and ultrahigh-pressure belt, northern Jiangsu Province, China. Diamond, rutile, kyanite, and marble metallogenic series, and phosphorus, quartz, and kyanite metallogenic series are presented on the basis of regional petrology, structural geology, metallogeny and mineralization age in northern Jiangsu Province. The former was formed when a huge amount of material from the Yangtze plate was subducted northwards beneath the North China plate. The latter is associated with the exhumation of the high-pressure and ultrahigh-pressure belt. The paper also discusses the existence of the Yanshanian gold, silver, and polymetallic metallogenic series. Its formation is related to the Yanshanian post-exhumation extension event.
